Simple. Scalable. Powerful.
Thermagix turns untapped heat into clean energy - quietly, efficiently, and affordably. This is the future of heat recovery.

​Thermoacoustics is a proven heat-to-energy conversion technology, successfully used by NASA and naval forces around the world.  Unlike traditional heat engines, thermoacoustic systems use sound waves as a “virtual piston”, eliminating the need for moving parts like pistons or valves.

This results in:

• High efficiency

• Low maintenance

•  Exceptional durability

• Quiet and reliable operation 

Traditional thermoacoustic systems have demonstrated efficiencies of up to 59% of the Carnot limit - an impressive benchmark.

However, to achieve useful power densities, these systems must operate at both high pressures (typically 20–170 bar) and high temperatures, which in turn requires:

• Expensive, high-performance components

• Compliance with demanding safety and certification standards

• Specialized materials and complex engineering

As a result, existing systems are costly to build, heavy, and difficult to scale for broader industrial use.

Thermagix has developed the next-generation solution: Phase-Change Thermoacoustics.

By integrating evaporation and condensation processes (phase-change) into the thermoacoustic cycle, we achieve:

• A 100x increase in power density

• Higher efficiency at significantly lower pressures

• The ability to harvest heat from sources as low as 60-100℃

• A lightweight, modular, and plug & play system design

This breakthrough dramatically reduces cost and complexity, while opening the door to low-grade heat recovery across a range of industries.

Thermagix’s innovation makes it possible to efficiently harness low-temperature heat sources that have long been difficult or uneconomical to recover at scale.

While some technologies have addressed parts of this challenge, Thermagix redefines what’s possible - making energy recovery from previously impractical sources truly viable. 

By reimagining how heat becomes power, Thermagix is paving the way toward a more efficient, scalable, and sustainable energy future.
